[compiler-rt] [fuzzer] Skip trying to set the thread name on MinGW (#115167)

Since b4130bee6bfd34d8045f02fc9f951bcb5db9d85c, we check for
_LIBCPP_HAS_THREAD_API_PTHREAD to decide between using
SetThreadDescription or pthread_setname_np for setting the thread name.

c6f3b7bcd0596d30f8dabecdfb9e44f9a07b6e4c changed how libcxx defines
their configuration macros - now they are always defined, but defined to
0 or 1, while they previously were either defined or undefined.

As these libcxx defines used to be defined to an empty string (rather
than expanding to 1) if enabled, we can't easily produce an expression
that works both with older and newer libcxx. Additionally, these defines
are libcxx internal config macros that aren't a detail that isn't
supported and isn't meant to be relied upon.

Simply skip trying to set thread name on MinGW as we can't easily know
which kind of thread native handle we have. Setting the thread name is
only a nice to have, quality of life improvement - things should work
the same even without it.

Additionally, libfuzzer isn't generally usable on MinGW targets yet
(Clang doesn't include it in the getSupportedSanitizers() method for the
MinGW target), so this shouldn't make any difference in practice anyway.

[compiler-rt][Fuzzer] SetThreadName windows implementation new try. (#76761)

SetThreadDescription symbol needs to be dynamically loaded before usage.
Then using a wide string buffer, since we re using a null terminated
string, we can use MultiByteToWideChar -1 as 4th argument to finally set
the thread name.

Previously `SetThreadDescription` was called directly causing crash.
It was reverted in dd3aa26fc8e9de37a39611f7a6a602bcb4153784
